BOARD-SUPPORT FOR SAWING-MACHINES.

' Specification of Letters Patent.

Application filed April 20, 1912.

To all whom it may concern:

Be it known that I, JERRY M. REED, a citizen of the United States,residing at Fort Thomas, in the county of Campbell and State ofKentucky, have invented certain new and useful Improvements in Board-Supports for SawingMachines, of which the following is a specification.

In sawing a board on a sawing machine, slivers are frequently broken offby the saw blade, and as the direction of the blade at the cutting pointis downward, there is a tendency to carry the slivers into the slot inthe board support. These slivers are frequently wedged in the slot sotightly that the saw is burned and ruined before the ma chine can bestopped and the sliver removed.

My invention relates to a device for sawing machines for supporting theboard being sawed, and the object of my invention is to provide a boardsupport to support a board while passing the saw blade and which willautomatically eject any slivers which may be broken off by the sawblade, and in arranging said board support so that it may be moved awayfrom the saw blade to release any slivers which might, by anypossibility, be wedged in the slot.-

The following description and claims and the annexed drawings set forthin detail the preferred method of carrying out my invention. The boardsupport may, however, be made in one piece, if desired, and it may besupported in any suitable way instead of on the saw guide as shown, andused on either band or circular saws.

Figure 1 is a side view of my invention shown in connection with a sawguide and a band saw blade, and with one side of the support thrown backaway from the saw blade. Fig. 2 is a plan view of the same, also shownin connection with the saw guide. Fig. 3 is a front view of the sameshown in connection with a saw guide and band saw blade, with a boardresting on the support. Fig. 4 is a perspective view of one side of thesupport, and Fig. 5 is an enlarged front end view thereof.

In the drawings, 1 represents the board support pivoted to the saw guide2 on bolts 3, and forming a slot 4 in which the band saw 5 is disposed.The edges 6 of the board support adjacent to the saw blade, or theinside edge, are tapered from the front or end near the saw teeth towardthe rear end,

and from the top or bearing surface of the support toward the under-sidethereof, forming a slot for the saw blade which in creases in width fromthe-front toward the rear end, and from the top or bearing surfacetoward the under-side.

The board support is supported and held in a horizontal positionby thescrews 7 taking into the lugs 8 on the saw guide 2. The screws 7 alsoserve as a means for leveling the board support and adjusting it up anddown. In practice, the position of the board alpport' must necessarilybe immediately er the saw guide, and the guide, therefore, offers themost convenient means of supporting the board support. If desired,however, the board support may be provided with a support independent ofthe band saw guide.

When the machine is in operation the board passes on eit-herside of thesaw blade and is supported by the board support as shown in Fig. 3. Theboard travels from the tooth-edge toward the back of the saw blade, andif a sliver is broken off and lodges bet-ween the board support and thesaw blade, the board pushes it along in the slot formed in the boardsupport, until it reaches a part of the slot wide enough to allow it topass through and drop to the floor. Or, if the sliver is too large topass through the slot, either one or both sides of the board support maybe thrown back from the saw blade while the machine is in motion, andthe sliver in that way quickly removed and the burning and injury to theblade thereby avoided.

Having fully described my invention, what I claim and desire to secureby Letters Patent, is I 1. A board support consisting of a supportingplate pivotally supported at its rear end, and having a slot for a sawblade, said slot extending lengthwise of said supporting plate andincreasing in width from the front toward the rear end thereof.

2. A board support consisting of a supporting plate pivotally supportedat its rear end, and having a slot for a saw blade, said slot extendinglengthwise of said supporting plate and increasing in width from thefront toward the rear end thereof, and from the top or bearing surfaceof the plate to the under-side.

i 3. A board support consisting of a supporting plate pivotallysupported at its rear end, and having a slot for a band saw bladeextending lengthwise of said supporting plate, and said slot increasingin width from the front toward the rear end thereof, and from the top orbearing surface of the plate toward the under-side, with means forpermitting the movement of the supporting plate away from the saw blade.

' 4. A board support consisting of supporting plates pivotally supportedat their rear ends, and forming a slot for a saw blade, said slotextending lengthwise of said supporting plates and increasing in widthfrom the front toward the rear end thereof, and

from the top of said plates toward the under-side, with means forpermitting the independent movement of each plate away from the sawblade.

5. In a sawing machine, the combination of a saw blade and a saw guidetherefor, of a board support consisting of one or more supporting platesfor supporting a board on either side of the saw blade, said boardsupport being pivotally supported at the rear end thereof, and forming aslot for the saw blade, said slot extending lengthwise of said boardsupport and increasing in width from the front toward the rear endthereof,

and from the top of said board support to the under-side, with means forpermitting the movement of said supporting plate or plates away from thesaw blade, substantially as described.
